Scharnebeck Comprehensive Municipality (SG)

§2(2) of the local Hauptsatzung just mentions colours. Mr. Christian Päpper from the local administration however told me that there are existing two different versions of the SG-Flag, one is green over yellow, the other yellow over green.

It is a yellow over white horizontal bicolour with centred arms. Beneath the arms is a black inscription in two lines "Gemeinde SCHARNEBECK". The 2nd line in capitals is bigger and the "A" is replaced by a red "A", shaped like a sail.
